You can't use tile sources directly in WMS layers, you need to put a cache in between. See http://mapproxy.org/docs/nightly/configuration.html#disable-storage if you don't want to use the actual cache.

It looks like https://bitbucket.org/olt/mapproxy/issue/39/parameter-format-non-defined-if-using
I think it is related to the use of a tile source, but I will check that, now that I have an example to reproduce this error.

It will use the SRS of the grid, so it should work.
